|iv|PRovEMENT `IN sEEo-PLANTERS.

i Specification forming part oi' Letters Patent No. 32,1 I7.. dated April 23, 1861.

o all whom t may concern: i

.Beit known that I, D. BRoY, ofCanton, in the county of Lewisl and State of Missouri, have invented a new and Improved Seed-Planter; and I do hereby dechire that the following is a full, clear, and exact description of the same, reference being had tothe accompanying drawings, making a part of this specication, in which- Figure l represents a longitudinal vertical section of my invention, the line a; x, Fig.`2, indicating the plane of section. Fig. 2 is a plan or top view ofthe same; Fig. 3 is avertical longitudinal section of the seed dropping device. i

Similar letters of reference in the three views indicate corresponding parts.4

The object ot'this invention is to arrange a seed-planter whichxwill open the furrows, drop" the seed, and cover it over with ease and, facility, and which allows ofregulating the depth to which the furrows are opened in a simple, sure, andready manner. y

To enable those skilled in the art to make and use my invention,`I will proceed to describe its construction and .operation with ret'- erence to the drawings. y y

The frame A is supported in the rear by the two coveringwheels B B, which are secured to the axle U, and in front by the sharp-ed ged flanged wheels D, which serve to Iout through the sod and to open the furrow. `The coverin g-whcels are provided with Hat-bottomed grooves o, lined with sheet-zinc or othersuitable material, and their sides are inclined, so that the dirt is pressed on the seed from both sides, and the wheels are ot such width that a flat portion is left on each side of the grooves, thus preventing saidwheels cutting into the ground and causing an undue pressure onthe seed. By giving to the grooves a a flat bottoms I `obviate the ditljculty arising with sharpangled grooves generally used with covering-rollers-namely, the liability ot such grooves to till with dirt.

The` cutting- Wheels D are provided with sharp-edged dan ges 1), which serve as the cutters, and the depth to which these cutters sink into the ground is determined by the rims c.

In order to be able to regulate the depth to which the cutters b work, I have attached the rims c by means of screws or rivets d, or by any other means which allow of easily removing it is operated by a hand-lever, G, from the drivers seat H. Thebottom of each ofthe hoppers is provided with an oblong slot,f, situated about in the center of said bottom and under a scraper, g, which forms the guide for the slide in the interior ofthe hopper, and

which at the same time serves to'scrape oit' the surplus seed from theseed-cells L. Two pairs of such seed-cells are made iueach end ofthe slide F, or" ditt'erent size,to sow mor-cor less grain, asmay be required, in each hill.

\ To prevent each set of seed-cells from sowing at the same time, I use inclined caps L in each hopper, to cover one set of seed-cells to `prevent their action when the other set is doing work. These caps'are made to t on either side of the seed-slide, so that either set oi' seedcells can be covered, as desired.

ground and ac- To determinethe amount of grain to be sown, I makeV grooves p in the slides, running out from the seed-cells ot suflcient length to prevent their rear or outer end from coming in contact with the scraper. By this connection of grooves and seed-c'ellsthe grain is not liable to be cracked or cut, as is the case with sharp-edged seed-cells.

The plows I are made straight on one side, and the other side shear shaped to open the furrow ot' suflcient 'width to deposit the grain in. ,The sides ofthe cutting wheels slightly' rub the plows near their points on their l straight sides, and their cuttingedges are a little-below the points of the plows. Without .this arrangement ot' plows and cutters thel plows are liable to clog-orchoke.

To. allow the machine to rise and fall in front to pass over obstructions, or to enable it to be turned around, I attach a lever, s, to the pole J, the front end of said lever being fastened to the frame and its rear end running back .under the drivers seat. By thus connecting the lever and pole the driver can easily raise the front part of the machine with his foot without changing his position on his seat. The draft-pole J is hinged tol a standard, R, attached to the cross-timber between the covering-wheels and above their axis, so that the strain exerted by the draftanimals on the lever bears down upon thc cuttingwheels to keep them to their work. The pole can be raised or lowered on the standard to vsuit the amount of .pressure that may be required on the cutting-Wheels. Without this arrangement of the draft-pole said cutting- Wheels would be liable to do their work imperfectly, and the-strain exerted by the draftpole on the lever is absolutely necessary to insure a correct action of said cuttingwheels under all circumstances, and to cause them to cut through the sod to the depth determined by the flanges c, which are attached to the sidesof the cutting-wheels D.

,To prevent a lateralv motion of the machine, and to enable it to follow the undulatons ot the ground,I use a guide, o, fastened in the front part of the machine, which passes through a slot or mortise in said pole, which makes a ,loose coupling there, and leaves the different parts free to do their proper work.

The operation of my seed -planter is very simple, it can easily be managed by one person, and all its parts are so constructed that 'they do not get easily out of order.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The arrangement of' the double perforated slide F,inclined cap L, tubes I,cuttingwheels D, and lever G, with the dat-bottomed grooved wheels B and adjustable tongue J, in the manner and for the purpose herein shown and described'. v
